Abstract
Provided is a sensing system for wireless and passive monitoring of strain during a manufacturing process that depends on force to apply the energy into the manufacturing process, the sensing system comprising: at least one surface acoustic wave (SAW) sensor for detecting strain, the at least one SAW sensor being positioned in a force path located on or in the structure of one or more objects under test; and at least one transceiving antenna arrangement being connectable to the at least one SAW sensor, wherein the at least one SAW sensor and the at least one transceiving antenna arrangement are arranged to receive energy from an interrogation signal and output a strain response signal detected by the at least one SAW sensor in response to the interrogation signal.
